For example : Button style and Appearance at Design time,

While at runtime Buttons look like as below,

Any help will be highly appreciated.

Answer 1

You are missing the call to:

        Application.EnableVisualStyles();

When added, in Main before displaying the Form you will get your expected behavior. If you are exporting this form in a dll you can still add this call inside the constructor of the form.
